Amid the morning-after punditry, there is one thing from last night's debate that people from almost every political viewpoint can agree on: Bernie Sanders wags his finger a lot. He used it to scold Clinton; he used it to signal to the moderators that he wanted to speak; he used it to express his disgust with the 1 percent. It was...unusual.

It's notable though, that Sanders was shaking his finger at women. He was the only man onstage (!), along with Secretary Clinton and moderators Judy Woodruff and Gwen Ifill. In that context, the finger wagging came off as especially imperious and condescending, as noted by many on Twitter. Some saw it as an example of mansplaining, though his supporters mostly just found it hilarious.
